Linux Mint上的Laravel和Composer安装

I have a Linux Mint machine I am working on. I want Laravel to install on it.

When I search for this I got this command: curl -sS https://getcomposer.org/installer | php from "https://getcomposer.org/download/" to put in terminal but it gives me this:

The program 'php' is currently not installed. You can install it by typing:
sudo apt-get install php5-cli
The program 'curl' is currently not installed. You can install it by typing:
sudo apt-get install curl

After i have done sudo apt-get install curl

libcurl3 curl

got this which is not successfully installed curl

How can any one I successfully install these things and Composer and Laravel?

The Composer already hints you the way to install those, you should run those commands, enter your password en those libraries should be installed automatically, after you install those libraries rerun the composer download.
